Ask anyone I know--I recently got super into rock climbing.
On a whim, I invested in a pair of shoes, a chalk bag, a bouldering gym membership, and a roll of tape. It's pretty rare for me to jump head-on into something so quickly, but I'm so glad I've invested in this hobby because it's starting to pay off.
When I hit the rock gym, my mind is instantly cleared. I'm no longer focused on student essays, lesson plans for the next week, or how my lesson may have crashed and burned that day. Instead, I'm faced by different issues--how to climb a particular route, how to best bandage a blister, how to catapult myself over a ledge--the list goes on. Rock climbing gives me a physical activity that embodies problem solving, and helps me process along the way.
Granted, not all problems are solved in a quick and clean fashion. Some problems take a few falls or a few fails before being solved, and I've learned to grow comfortable in those times.
I'm learning to grow comfortable when I fail at teaching as well.
Don't get me wrong--I hold myself to a very high standard, but teaching is a try-and-fail setup. If you try an activity and you fail, you try again or you move on to something that may work. If you fail at getting a point across, you stand up, brush yourself off, and come back the next day to try again.
I'm so thankful I found rock climbing in my first year of teaching so I could learn to fall, learn to fail, and practice getting back up time and time again.
